DD1's 21st dress + broken ankle shoe horror. Need help

[Awks]

Need a distraction tonight so dd1 and I are thinking about her 21st in 2 weeks and the trauma that is shoes. She has her dress (below) but is partially weight bearing after a broken ankle caused by falling of stupidly high heels, when drunk but she needs shoes. She's tried low flats with ankle straps but thinks they make her look cankley.

Any ideas? www.asos.com/Lashes-of-London/Lashes-Of-London-Prom-Dress-With-Fluro-Scallop-Bustier/Prod/pgeproduct.aspx?iid=2793906&SearchQuery=lashes%20of%20london&sh=0&pge=0&pgesize=20&sort=-1&clr=Multi

What about some sparkly flat sandals, like these? Particularly if the weather's hot.

What about wedges>? They're nowhere near as difficult as heels and if she gets summery cork ones they won't be too heavy for her mending ankle

example

Maybe not for all night but for pictures etc and then flats for later?

Is she a 4?
surely these are about spot on?

Oh, feck, totally rhe wrong linkhere the blowfish ones are grand but there's not enough green in the yellow

these would work too

TYVM. We've looked at all these and there are some really brilliant ideas. She loves the KG wedges but can't gte her ankle to bend that far yet. The coloured ballet low wedgey type flats are the faves but the colours arent right but the style is. You are all so kind to look and she has a style now so ta very x
